  Hilo, 
  is 
  closely 
  allied 
  to 
  the 
  remarkable 
  Tantalus 
  species, 
  which 
  

   I 
  specially 
  noticed 
  in 
  last 
  year's 
  address 
  on 
  the 
  insects 
  of 
  that 
  

   mountain. 
  The 
  giant 
  species 
  of 
  Scoiorythra 
  are 
  common, 
  and 
  

   the 
  still 
  larger 
  Acrodrepanis 
  occurs 
  on 
  the 
  Olaa 
  side. 
  Six 
  out 
  of 
  

   eight 
  of 
  the 
  native 
  species 
  of 
  Leucania 
  occur, 
  and 
  all 
  of 
  the 
  most 
  

   remarkable 
  species. 
  Species 
  of 
  Scoparia 
  are 
  a 
  feature 
  of 
  the 
  lo- 
  

   cality 
  being 
  extremely 
  numerous, 
  as 
  also 
  are 
  individuals 
  of 
  

   several 
  species 
  of 
  Ortkomecyna 
  and 
  Mestolobes. 
  Many 
  other 
  nice 
  

   Pyralidina 
  are 
  conspicuous, 
  species 
  of 
  Margaronia, 
  Omiodes, 
  

   Phlyctaenia, 
  Talis 
  and 
  the 
  remarkable 
  Hyperectis, 
  Vv^hile 
  a 
  Ptero- 
  

   phorid 
  swarms 
  amongst 
  the 
  Vaccinium. 
  Tineina 
  are 
  in 
  profusion 
  

   at 
  certain 
  (and 
  irregular) 
  seasons, 
  and 
  a 
  number 
  of 
  large 
  species 
  

   of 
  Tortricina 
  occur, 
  but 
  the 
  latter 
  are 
  generally 
  scarce. 
  The 
  

   Microlepidoptera 
  require 
  special 
  collecting. 
  They 
  should 
  always 
  

   be 
  killed 
  with 
  ammonia 
  and 
  pinned 
  in 
  the 
  field 
  on 
  silver 
  wires, 
  

   directly 
  they 
  are 
  caught. 
  I 
  shall 
  not 
  attempt 
  to 
  draw 
  up 
  a 
  list 
  

   of 
  species 
  of 
  this 
  Order, 
  w^hich 
  would 
  be 
  of 
  great 
  length, 
  the 
  

   genera 
  Agrotis, 
  Leucania, 
  Scoiorythra 
  and 
  Scoparia 
  including 
  

   many 
  species. 
  The 
  butterfly 
  Pyrameis 
  tameamea 
  is 
  very 
  

   abundant 
  and 
  very 
  variable 
  in 
  color 
  on 
  the 
  underside, 
  while 
  the 
  

   little 
  blue, 
  Lycaena 
  hlackhumi, 
  swarms 
  on 
  the 
  bushes 
  of 
  Dodonaca 
  

   viscosa, 
  on 
  which 
  the 
  caterpillar 
  feeds. 
  

  

  DIPTERA. 
  

  

  The 
  flies 
  are 
  represented 
  by 
  numerous 
  endemic 
  species, 
  mostly 
  

   very 
  small 
  and 
  obscure 
  forms. 
  The 
  Drosophilidae 
  and 
  Dolich- 
  

   opodidae 
  include 
  most 
  of 
  these, 
  and 
  they 
  are 
  probably 
  still 
  more 
  

   abundant 
  at 
  lower 
  elevations 
  in 
  Olaa. 
  Most 
  conspicuous 
  are 
  the 
  

   Sarcophagid 
  flies 
  of 
  the 
  genus 
  Dyscritomyia 
  and 
  Prosthetochaeta. 
  

   They 
  m.ay 
  be 
  seen 
  buzzing 
  round 
  the 
  herbage 
  or 
  shrubs 
  in 
  a 
  very 
  

   Tachina-like 
  manner 
  and 
  in 
  fact 
  often 
  in 
  company 
  with 
  these 
  

   parasites. 
  Their 
  habits 
  are 
  yet 
  unknown. 
  I 
  had 
  long 
  supposed 
  

   them 
  to 
  be 
  parasitic 
  on 
  cutworms, 
  but 
  the 
  discovery 
  by 
  Mr. 
  

   Terry, 
  that 
  they 
  produce 
  living 
  maggots 
  of 
  large 
  size, 
  makes 
  this 
  

   supposition 
  less 
  probable. 
  The 
  fact 
  that 
  they 
  often 
  frequent 
  

   the 
  driest 
  and 
  most 
  arid 
  localities, 
  where 
  there 
  is 
  little 
  or 
  no 
  

   decaying 
  vegetable 
  matter, 
  and 
  that, 
  in 
  other 
  places 
  where 
  such 
  

   matter 
  exists, 
  one 
  does 
  not 
  find 
  fly 
  maggots 
  therein, 
  that 
  could 
  

   produce 
  these 
  large 
  species; 
  the 
  further 
  fact 
  that 
  animal 
  matter 
  

   under 
  natural 
  conditions 
  in 
  the 
  islands 
  was 
  necessarily 
  almost
